Definitions

  • the present invention relates to a solid cosmetic preparation, specifically to a solid cosmetic preparation comprising a plastic fat mainly consisting of a mixed acid triglyceride of a straight-chain saturated fatty acid having 20 or more carbon atoms and an unsaturated fatty acid having 16 to 22 carbon atoms which contains, as the constituent fatty acids, 30 to 70 wt.% of said saturated fatty acid having 20 or more carbon atoms and 20 to 60 wt.% of said unsaturated fatty acid having 16 to 22 carbon atoms.
  • Representative solid cosmetic preparations include bar-like ones such as lipsticks, lip cream, foundation sticks, and stick pomade; pencil-like ones such as eyebrow pencils and eyeliner pencils; pressed powders such as foundation, eye shadow, and rouge; and oily cake-like ones.
  • conventional oily cosmetic preparations are those containing a powder dispersed in a mixed system of a-solid fat such as carnauba wax, candelilla wax, ceresin, microcrystalline wax, hardened animal or vegetable oil, or beeswax, with a liquid or semi-liquid oil such as castor oil, olive oil, jojoba oil, squalane, a synthetic ester oil, silicone oil, liquid paraffin, or vaseline.
  • a-solid fat such as carnauba wax, candelilla wax, ceresin, microcrystalline wax, hardened animal or vegetable oil, or beeswax
  • a liquid or semi-liquid oil such as castor oil, olive oil, jojoba oil, squalane, a synthetic ester oil, silicone oil, liquid paraffin, or vaseline.
  • an excellent cosmetic preparation can be obtained by blending, in its formulation, a plastic fat mainly consisting of a mixed acid triglyceride of a straight-chain saturated fatty acid having 20 or more carbon atoms and an unsaturated fatty acid having 16 to 22 carbon atoms which contains, as the constituent fatty acids, said saturated fatty acid having 20 or'more carbon atoms and said unsaturated fatty acid having 16 to 22 carbon atoms.
  • a solid cosmetic preparation according to the invention comprises a fat and oil composition, called also a plastic fat, comprising (1) as the main triglyceride one or more mixed acid triglyceride having one or two straight, saturated C20 to C26, preferably C20 to C24, fatty acid residues and one or two unsaturated C16 to C22 fatty acid residues in a molecule thereof and (2) comprising in the entire fatty acid moiety 15 to 70 wt.% of one or more saturated C20 to C26, preferably C20 to C24, fatty acids and 20 to 60 wt.% of one or more unsaturated C16 to C22 fatty acids. It is useful as a base of a solid cosmetic preparation.
  • said composition comprises 30 to 70 wt.%, more preferably 40 to 65 wt.%, of one or more saturated fatty acids having 20 or above, especially 20 to 24, carbon atoms. It is also preferable that the unsaturated fatty acids are contained in an amount of 25 to 50 wt.% in the composition.
  • a preferable embodiment of the solid cosmetic preparation comprises 0.1 to 80 percent by weight of said composition and 99.9 to 20 percent by weight of one or more conventional cosmetic components.
  • composition comprises 35 wt.% or more of the mixed acid triglyceride.
  • the solid cosmetic preparation of the invention is so oily as to have a good spread and lustre and a high flexibility. It also has a reduced tendency to change in hardness with a temperature change, but no liability to deteriorate in quality owing to sweating or blooming.
  • the preparation is of the pressed powder type, having an excellent impact resistance and a good feeling in use and developing no shininess.
  • the solid cosmetic preparation of the invention may further include an alpha-mono(methyl-branched alkyl)glyceryl ether of the formula (1) in which m is an integrer of 2 to 14, n is an integer of 3 to 11 and the total of m and n is 9 to 21.
  • the preparation may further comprise a cholesteryl ester of a branched fatty acid of the formula (2) in which R is a saturated aliphatic hydrocarbon group having 11 to 23 carbon atoms and at least one alkyl substituent between the carboxyl-bonded position and the center of the main chain thereof.
  • the solid cosmetic prepration provides preferable embodiments which further comprise the above shown glyceryl ether (1) and/6r the above defined cholesteryl ester (2).
  • the embodiments provide a satisfactory shape retention, feeling in use, finish and wear.
  • plastic fat used in the present invention when blended in a cosmetic preparation, exerts a remarkable feeling- improving effect including very good spread and soft touch in application thereof to the skin. It has also been found that the finish and wear are improved to some extent, but the improving effect is yet insufficient and unsatisfactory.
  • Utilization of an a-mono(methyl-branched alkyl)glyceryl ether in a cosmetic preparation as used in the present invention has already been disclosed in Japanese Patent Laid-Open No. 120,508/ 1982, which teaches that the utilization prevents deterioration of the appearance quality, reduction in the breaking strength, and worsening of feeling in use caused by sweating and blooming during the storage of a bar-like cosmetic preparation. It has also been found that the finish and wear are improved to some extent, but the improving effect is yet insufficient and unsatisfactory.
  • the inventors of the present invention has found that blending of the above-mentioned plastic fat together with an a-mono(methyl-branched alkyl)-glyceryl ether in a cosmetic preparation provides a marked synergistic effect.
  • the plastic fat to be contained in the cosmetic preparation of the present invention mainly consists of a mixed acid triglyceride of a di-saturated and mono-unsaturated type mainly having two straight-chain saturated acyl groups in the molecule. At least one of the straight-chain saturated acyl groups in the mixed acid triglyceride has 20 or more carbon atoms, preferably 20 to 26 carbon atoms, while the other straight-chain saturated acyl group has 16 or more carbon atoms, preferably 16 or 26 carbon atoms.
  • the unsaturated acyl group has 16 to 22 carbon atoms. Above all, it is more preferred that both of the two straight-chain saturated acyl groups have 20 to 26 carbon atoms.
  • the remaining component of the plastic fat is triglycerides comprising, as the constituent fatty acids, straight chain saturated fatty acids having 8 or more carbon atoms and/or unsaturated carbon atoms having 8 or more carbon atoms.
  • the preferred number of carbon atoms in those fatty acids is 16 to 24. Where the number of carbon atoms in the constituent fatty acid is 8 or less, there arise fears of bad smell and skin stimulation caused by hydrolysis..
  • the term "mainly consisting of a mixed acid triglyceride of a saturated fatty acid having 20 or more carbon atoms and an unsaturated fatty acid having 16 to 22 carbon atoms” is intended to mean that it is the most abundant component of triglycerides with a content of the above-mentioned mixed acid triglyceride of the di-saturated and mono-unsaturated type in the plastic fat of usually about 35% or more, preferably 45% or more.
  • Unsaturated fatty acids with 16 to 22 carbon atoms which can constitute the above-mentioned plastic mixed acid triglyceride include oleic, linolic, and linolenic acids, the bonding position of which may be either an a position or a 0 position, preferably both of them to provide a mixture.
  • the position and number of unsaturated bonds in the unsaturated fatty acids are not limited, the preferred number of the unsaturated bonds is 1 or 2 from the viewpoint of oxidation stability.
  • Usable straight-chain saturated fatty acids with 20 or more carbon atoms include arachic and behenic acids. The especially preferred number of carbon atoms in them is in a range of 20 to 26, out of which slightly poor flexibility may ensue. Where the number of carbon atoms is 18 or less, the crystallinity is apparently high to lead to brittleness, with the result that the above-mentioned performance cannot be exhibited when blended into a solid cosmetic preparation.
  • the content of the above-mentioned plastic fat in the solid cosmetic preparation of the present invention is different depending on the shape of the preparation, and can be in a range of 0.1 to 80 wt.%, preferably 0.2 to 50 wt.% in usual. When it is below the range, no sufficient effect can be secured. On the other hand, when it is above the range, the effect is saturated only with an economical disadvantage, and the feeling in use is deteriorated with poor spread, etc. due to the appearance of the properties of the plastic fat itself in the cosmetic preparation, to the detriment of the performance of the cosmetic preparation.
  • the process of preparing the plastic fat to be used in the present invention is not particularly limited.
  • the plastic fat can be obtained according to, for example, the process disclosed in Japanese Patent Laid-Open No. 53,598/1985.
  • Preferred a-mono(methyl-branched alkyl)-glyceryl ethers represented by the formula (1) to be used in the present invention are those having a sum of m and n of 13 to 17 (namely a total number of carbon atoms in the alkyl'group of 16 to 60). More preferred are those having a sum of m and n of 15 (namely a total number of carbon atoms in the alkyl group of 18).
  • the branched methyl group is preferably positioned close to the center of the main alkyl chain.
  • the content of the above-mentioned a-mono-(methyl-branched alkyl)glyceryl ether in the solid cosmetic preparation is different depending on the shape of the preparation, and can be in a range of 0.1 to 10 wt.%, preferably 0.5 to 8 wt.% in usual. When it is below the range, no sufficient effect can be secured. On the other hand, when it is above the range, an influence on the physical properties , of the fat appears, and there may arise a problem of shape retention, including a decreased breaking strength, for example, in the case of lipsticks.
  • a process of preparing an a-mono(methyl-branched alkyl)glyceryl ether to be used in the present invention is disclosed in Japanese Patent Laid-Open No. 133,281/1981.
  • the process of preparing an a-mono(methyl-branched alkyl)glyceryl ether to be used in the present invention is not limited to this.
  • Branched fatty acids (RCOOH) to be used in the preparation of the cholesteryl ester of the branched fatty acid that may be used in the present invention include those having 12 to 24 carbon atoms (11 to 23 carbon atoms in R). Preferred are those having 14 to 20 (13 to 19 carbon atoms in R).
  • the branched fatty acid is a saturated one having at least one alkyl substituent between the carboxyl group-bonded position and the center of the main chain.
  • Such branched saturated fatty acids are easily obtained from raw materials in the petrochemical and fat industries.
  • Such branched saturated fatty acids obtained from raw materials in the petrochemical industry include those having a side chain at the a position and represented by the following formula: (wherein R 1 and R 2 are each a straight-chain or branched saturated aliphatic hydrocarbon group, and the sum of carbon atoms in R 1 and R 2 is 12 to 18).

  • methyl-branched isostearic acid obtained as a by-product in the production of a dimer of oleic acid.
  • its isopropyl ester is commercially available (Emery Industries, Inc., USA, etc.).
  • the cholesteryl ester of the branched fatty acid that may be contained in the cosmetic preparation of the present invention is prepared from the above-mentioned branched fatty acid or a derivative thereof and cholesterol according to a customary ester preparation process.
  • the content of the above-mentioned cholesteryl ester of the branched fatty acid in the solid cosmetic preparation is different depending on the shape of the preparation, and can be in a range of 0.01 to 50 wt.%, preferably 0.03 to 30 wt.% in usual. When it is below the range, no sufficient effect can be secured. On the other hand, when it is above the range, the effect is saturated only with an economical disadvantage, and problems including appearance of stickiness are liable to arise due to the appearance of the properties of the cholesteryl ester of the branched fatty acid itself.
  • a process of preparing the cholesteryl ester of the branched fatty acid that may be used in the present invention is disclosed in Japanese Patent Laid-Open No. 65,900/1981.
